The wood of Birnam.

We doubt it nothing.

Who then shall blame
His pester'd senses to recoil and start,
When all that is within him does condemn
Itself for being there?

What does the tyrant?

The English power is near, led on by Malcolm,
His uncle Siward and the good Macduff:
Revenges burn in them; for their dear causes
Would to the bleeding and the grim alarm
Excite the mortified man.
